Question

A charge of `16 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `32 J` to `4 J`, what is the voltage between points A and B?

Answer 1

The voltage is `=1.75V`

Explanation:

Apply the equation

`"Energy"(J)"` `= " Electric potential(V)"xx"Charge (C)"`

The charge is `Q=16C`

The energy is `DeltaE=32-4=28J`

The voltage is

`U=(DeltaE)/(Q)=28/16=1.75V`
